Description

Technical Field

[0001] The invention relates to the technical field of refrigeration equipment production, and in particular to an evaporating fin assembly device. Background Art

[0002] With the continuous development of society, people have higher requirements for the comfort of working and living environments. Therefore, various types of refrigeration equipment have emerged. In refrigeration equipment, the evaporator is a very important device. Among them, the core structure of the evaporator is the fin. The fins are arranged side by side to effectively increase the contact area with the air, thereby exchanging heat with the air and cooling the hot air.

[0003] During actual assembly, it is necessary to set the mounting plates side by side in advance, then place the fins in a vertical state and align the pre-opened mounting grooves on the fins with the mounting plates. After alignment, press down the fins so that the mounting plates are fully embedded in the mounting grooves. In this way, the assembly of the fins is completed. Although the aforementioned assembly process can be completed manually. However, in order to adapt to different types of refrigeration equipment, the sizes of evaporators are different. The larger the size of the evaporator, the longer the length of the fins. Although the fins are made of metal materials, they are thin and relatively soft. This results in that as the length of the fins increases, it becomes increasingly difficult for the human hand to apply force evenly to the fins during the manual assembly process, which can easily cause the fins to deform and affect the heat exchange effect of the evaporator. Summary of the invention

[0004] In view of the technical problems in the prior art, the present invention provides an evaporating fin assembly device.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] An evaporator fin assembly device comprises: a pressing device and a feeding device; the feeding device comprises a hopper, a discharging roller and a guide plate; the hopper is arranged at an angle; a cavity for accommodating fins is provided in the hopper; a discharging port is provided at the lower end of the hopper; the discharging roller corresponds to the discharging port; the discharging roller is parallel to the fins; the discharging roller extends into the discharging port to contact the fins; the guide plate is arranged at an angle; one end of the guide plate corresponds to the discharging port, and the other end corresponds to the mounting plate; the pressing device comprises a pressing plate, a smoothing plate and a driving device; the pressing plate is arranged in a vertical direction; a through groove corresponding to the mounting plate is provided on the pressing plate; the smoothing plate is perpendicular to the pressing plate; the driving device is connected to the pressing plate in a transmission manner to drive the pressing plate to move in a vertical direction relative to the mounting plate; the driving device is connected to the smoothing plate in a transmission manner to drive the smoothing plate to move in a vertical direction relative to the mounting plate.

[0007] During actual operation, the staff puts the fins into the silo side by side. Because the silo is set at an angle, after the fins are put into the silo, the fins slide toward the end of the silo with the discharge port under the action of gravity, and finally fit with the discharge roller. Under the action of the friction between the discharge roller and the fins, the fins maintain the current state. When the fins need to be assembled, the discharge roller is controlled to rotate. When the discharge roller rotates, under the action of the friction between the two, the discharge roller pushes the fins out through the discharge port. Then the fins fall on the guide plate. Because the guide plate is set at an angle, the fins slide along the guide plate to the pre-arranged mounting plate. At this time, the fins are parallel to the ground. Then, the drive device is started. Driven by the drive device, the pressure plate moves in the vertical direction, thereby pressing on the fins, causing the fins to flip. In this way, the fins are assembled on the mounting plate. Because the pressure plate is in full contact with the fins, the force on the fins is relatively uniform, which effectively prevents deformation in the aforementioned process. When the pressing plate is completed, the driving device drives the smoothing plate to move, and the smoothing device continues to squeeze the fins so that the fins are fully assembled on the mounting plate. Therefore, during the process of assembling the fins, the present invention can evenly apply force to the fins, thereby preventing the fins from deforming during the assembly process, thereby effectively meeting the assembly requirements of fins with longer lengths.

[0008] Furthermore, the feeding device also includes a feeding plate; the feeding plate is parallel to the fins; the feeding plate is slidably arranged in the silo; and a slide rail corresponding to the feeding plate is provided in the silo.

[0010] Furthermore, the feeding device also includes a feeding motor; the feeding motor is arranged at the lower end of the silo; the feeding motor is connected to the silo; the output end of the feeding motor is connected to the discharge roller to drive the discharge roller to rotate relative to the silo.

[0011] Furthermore, the driving device includes a driving motor, a driving structure, and a transmission wheel; the number of the driving structures is two; the two driving structures are connected through a transmission wheel; one of the driving structures is connected to the output end of the driving motor and to the pressure plate; and the other driving structure is connected to the smoothing plate.

[0012] Furthermore, the driving structure includes a driving wheel, a driving rod, a connecting rod, and a transmission wheel; one of the driving wheels is connected to the output end of the driving motor; the transmission wheel is arranged between the two driving wheels; the transmission wheel is meshed with the driving wheel; one end of the driving rod coincides with the center of the driving wheel and is fixedly connected to the driving wheel; the other end of the driving rod is swingably connected to the connecting rod.

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] An evaporating fin assembly device comprises: a pressing device 1, a feeding device 2, a lifting cylinder 3, and a slider rail 4. The pressing device 1 is connected to the feeding device 2. One end of the lifting cylinder 3 is connected to the pressing device 1, and the other end is connected to the slider rail 4. Thus, the lifting cylinder 3 and the slider rail 4 cooperate to adjust the height and horizontal position of the pressing device 1 and the feeding device 2.

[0027] Specifically, the feeding device 2 includes a silo 21, a discharging roller 22, a guide plate 23, a feeding plate 24, a limit plate 25, and a feeding motor 26. A cavity for accommodating fins is provided in the silo 21. The silo 21 is tilted, so the bottom of the silo 21 is an inclined slope. At the same time, a discharging port 211 is provided at the lower end of the silo 21, and the width of the discharging port 211 matches the width of the fin so that only one fin can pass through at a time. On the other hand, the feeding plate 24 is parallel to the fin. At the same time, a slide rail corresponding to the feeding plate 24 is provided in the silo 21, and the feeding plate 24 is slidably connected to the silo 21 through the slide rail. Therefore, through the cooperation between the silo 21 and the feeding plate 24, when the fin is placed in the silo 21 in a vertical state, the fin will slide toward the discharging port 211 under the action of gravity. At the same time, the feed plate 24 also slides toward the discharge port 211 under the action of gravity, thereby squeezing the fins, so that the fins can maintain a vertical state during the sliding process, and prevent the fins from spreading after being placed in the silo 21. And the feed plate 24 is arranged parallel to the fins, so that the feed plate 24 is in full contact with the fins, and the feed plate 24 only squeezes the fins by its own weight, and the squeezing force on the fins is relatively small. Therefore, the deformation of the fins in the silo 21 can be effectively avoided.

[0028] The discharge roller 22 is rotatably connected to the silo 21, the discharge roller 22 is parallel to the fins, the discharge roller 22 corresponds to the discharge port 211, and the discharge roller 22 extends into the discharge port 211 so as to be in contact with the fins. At the same time, the feed motor 26 is disposed at the lower end of the silo 21 and connected to the silo 21. The output end of the feed motor 26 is connected to the discharge roller 22, so as to drive the discharge roller 22 to rotate relative to the silo 21.

[0029] The guide plate 23 is tilted and the tilting direction is the same as that of the silo 21. The lower end of the guide plate 23 corresponds to the mounting plate for assembling the fins, and is provided with a through groove matching the mounting plate. The higher end of the guide plate 23 corresponds to the discharge port 211. The limit plates 25 are respectively arranged on both sides of the guide plate 23. The spacing between the limit plates 25 corresponds to the length of the fins. At the same time, the limit plates 25 are connected to the pressing device 1, and one end of the limit plate 25 is connected to the guide plate 23, and the other end is connected to the silo 21.

[0030] The pressing device 1 includes a pressing plate 11, a caressing plate 12, a driving device 13, a shell 14, and a lifting spring 15. The shell 14 is covered on the pressing plate 11, the caressing plate 12, and the driving device 13. The pressing plate 11 is arranged in the vertical direction, and a through groove 111 corresponding to the mounting plate is provided on the pressing plate 11. Thus, the mounting plate can extend into the through groove 111 so as to be combined with the pressing plate 11. The caressing plate 12 is a rectangular plate. The caressing plate 12 is arranged in the horizontal direction. That is, the caressing plate 12 is perpendicular to the pressing plate 11. At the same time, T-shaped protrusions are provided on both sides of the pressing plate 11 and the caressing plate 12, and a sliding groove corresponding to the T-shaped protrusion is provided on the inner wall of the shell 14 in the vertical direction. Thus, the pressing plate 11 and the caressing plate 12 can be slidably connected to the shell 14, and the sliding direction of the two is the vertical direction. The lifting spring 15 is arranged between the caressing plate 12 and the shell 14. One end of the lifting spring 15 is connected to the caressing plate 12 through a T-shaped protrusion, and the other end is connected to the housing 14 .

[0031] The driving device 13 includes a driving motor 131, a driving structure 132, and a transmission wheel 133. The driving motor 131 is mounted on the housing 14. The transmission wheel 133 is rotatably connected to the housing 14. The number of the driving structure 132 is two groups. The driving structure 132 includes a driving wheel 1321, a driving rod 1322, and a connecting rod 1323. The driving wheel 1321 is rotatably connected to the housing 14. One end of the driving rod 1322 coincides with the center of the driving wheel 1321 and is fixedly connected to the driving wheel 1321, and the other end of the driving rod 1322 is swingably connected to the connecting rod 1323. At the same time, the transmission wheel 133 is arranged between the two driving wheels 1321, so that it can mesh with the two driving wheels 1321 at the same time. On the other hand, one of the driving wheels 1321 is provided with a toothed portion and a toothless portion. The toothed portion can mesh with the transmission wheel 133, and the toothless portion cannot mesh with the transmission wheel 133. The driving wheel 1321 is connected to the output end of the driving motor 131, so that the toothed portion and the toothless portion can cyclically correspond to the transmission wheel 133. One of the connecting rods 1323 is swingably connected to the pressing plate 11, and the other connecting rod 1323 is swingably connected to the smoothing plate 12.

[0032] For the convenience of description below, the units spaced apart from each other on the fin are defined as blades, the grooves formed by the spacing between the blades are defined as mounting grooves, and the area where the blades are connected together is defined as a connecting plate.

[0033] In actual operation, the mounting plate is arranged in advance by a fixture, which is a prior art and meets the subsequent assembly requirements, and is not described in detail here. At the same time, the position of the pressing device 1 and the feeding device 2 is adjusted by the lifting cylinder 3 and the slider rail 4, so that the mounting plate can extend into the through groove on the guide plate 23.

[0034] Afterwards, the staff member pre-adjusts the feed plate 24 so that the feed plate 24 is located at the higher end of the silo 21. Then, several fins are placed in the silo 21 with the connecting plate facing the bottom of the silo 21. At this time, the discharge port 211 and the feed plate 24 are respectively located at the two ends of the fin. Under the influence of gravity, the fin slides toward the discharge port 211. The feed plate 24 pushes the fin toward the discharge port 211 by its own weight, and supports the fin to maintain the fin in a vertical state. At the same time, because the silo 21 is set in an inclined state, the connecting plate of the fin fits the bottom of the silo 21, which makes the two adjacent fins staggered up and down, thereby reducing the contact area between the two adjacent fins, and then facilitating the separation of the two adjacent fins. In summary, when a group of fins is placed in the silo 21, the two fins at the head and tail are in contact with the discharge roller 22 and the feed plate 24 respectively. Due to the friction between the discharge roller 22 and the fin, the fin cannot fall through the discharge port 211.

[0035] When the fin needs to be output, the feeding motor 26 is started. Driven by the feeding motor 26, the discharging roller 22 starts to rotate, so that under the action of friction, the discharging roller 22 pushes the fins that fit together through the discharging port 211. When the fins are separated from the silo 21 through the discharging port 211, the connecting plate of the fins will contact the guide plate 23. The distance from the contact area between the connecting plate and the guide plate 23 to the discharging port 211 is less than the height of the fins. At this time, the discharging port 211 and the guide plate 23 provide a fulcrum on both sides of the fins, and the guide plate 23 is inclined. As a result, the fins will fall in a specific direction as shown in the accompanying drawings. After the fins fall on the guide plate 23, the fins will slide along the guide plate 23 to the mounting plate. At this time, the fins are parallel to the ground and the mounting grooves are in a state corresponding to the mounting plate. At the same time, during the sliding process of the fins, the two ends of the fins are restricted by the limiting plates 25. As a result, uncontrollable skewness of the fins can be avoided.

[0036] At this point, the output of the fins is completed. As mentioned above, the feed plate 24 is in full contact with the fins, thereby avoiding local excessive force on the fins and causing deformation of the fins. The fins are placed in the hopper 21 in an inverted position (the blades are on top and the connecting plates are on the bottom), and the discharge roller 22 is in contact with the connecting plate of the fins, so that the contact area between the discharge roller 22 and the fins is maximized, thereby making the ejection process more stable. At the same time, when the fins fall on the guide plate 23, the connecting plate is in contact with the guide plate 23, thereby effectively avoiding deformation of the blades caused by the impact of the falling fins. In summary, the output process of the fins is relatively stable and not prone to deformation.

[0037] After the fin falls on the mounting plate, the position of the pressing plate 11 is adjusted by lifting the cylinder 3 and the slider rail 4 so that the end of the pressing plate 11 is aligned with the connection between the blade and the connecting plate (hereinafter referred to as the connection). Subsequently, the drive motor 131 is started, and the corresponding driving wheel 1321 is rotated under the drive of the drive motor 131, thereby driving the corresponding driving rod 1322 to rotate synchronously, and then driving the connecting rod 1323 to swing synchronously. Finally, the pressing plate 11 is pressed down in the vertical direction. When the pressing plate 11 is pressed down, the pressing plate 11 will apply pressure to the connection. Under the action of pressure, the fin flips as shown in the attached figure. When the pressing plate 11 moves to the extreme position, the fin is completely flipped into a vertical state and fully fits with the pressing plate 11. At this time, the mounting plate extends into the mounting groove of the fin. Thus, the assembly of the fin is completed. In summary, compared with the assembly method of the prior art (as shown in the attached figure, the fins are directly plugged into the mounting plate in the vertical direction), the present invention makes it easier for the pressure plate 11 to apply force to the fins during assembly, and the pressure plate 11 is in full contact with the fins, thereby effectively preventing the fins from deforming. When the fins are assembled, the drive motor 131 is controlled to stop, and the slider rail 4 is controlled to move, so as to push the fins to the specified position on the mounting plate through the pressure plate 11. In this way, the fins on the mounting plate can fit each other as required.

[0038] On the other hand, during the process of pressing down the pressing plate 11, the toothless portion on the corresponding driving wheel 1321 corresponds to the transmission wheel 133. At this time, the transmission wheel 133 does not rotate. After the position adjustment of the fin is completed, the driving motor 131 is controlled to continue to operate. Driven by the driving motor 131, the toothed portion rotates to the transmission wheel 133, thereby engaging with the transmission wheel 133. As a result, the two driving wheels 1321 are engaged together through the transmission wheel 133. At this time, under the transmission of the transmission wheel 133, the two driving wheels 1321 rotate synchronously, and driven by the driving wheel 1321, the pressing plate 11 rises and the stroking plate 12 begins to descend. As a result, the stroking plate 12 will contact the connecting plate of the fin, thereby further pressing down the fin, so that the fin is further assembled with the mounting plate. As a result, the situation in which the fin is not fully assembled with the mounting plate during the flipping process of the aforementioned fin can be effectively avoided. Subsequently, the stroking plate 12 begins to rise, and the pressing plate 11 is still in the process of rising. Finally, the stroking plate 12 and the pressing plate 11 return to their initial positions. At this time, the toothless portion rotates to a position corresponding to the transmission wheel 133. Thus, the next cycle can be started. On the other hand, during the descent of the caressing plate 12, the lifting spring 15 will be stretched, and then, during the ascent of the caressing plate 12, the continued elastic force of the lifting spring 15 will be gradually released. When the toothless portion rotates to a position corresponding to the transmission wheel 133, the lifting spring 15 will bear the weight of the caressing plate 12 to prevent the caressing plate 12 from falling uncontrollably. In summary, the pressing plate 11 and the caressing plate 12 act successively, on the one hand, to provide sufficient space for the flipping of the fins, to avoid interference between the fins and the caressing plate 12 during the flipping process. On the other hand, the fins and the mounting plate can be fully assembled to avoid the gap between the fins and the mounting plate after the fins are flipped to a vertical state. At the same time, the aforementioned action process is completed by the drive motor 131 alone, which effectively reduces the number of power sources, thereby making the structure of the device more compact and occupying less space. And the drive motor 131 does not need to be reversed in the aforementioned process, which helps to extend the service life of the drive motor 131.

[0039] Thus, by continuously repeating the above process, the fins can be assembled on the mounting plate as required. In summary, the present invention fully contacts the fins during the discharging stage and the assembly stage, and the force on the fins is more uniform, thereby effectively avoiding deformation of the fins during the assembly process, and thus being able to effectively meet the assembly requirements of fins with longer lengths.
